A screen, region recorder, BB FlashBack is a cheaper alternative to Macromedia Captivate, if you are looking for a nominal cheap solution for software demonstrations, presentations, tutorials and training.
If you are not really looking for the all the enhanced features of Captivate, then this can prove to be a good solution.
Macromedia recently released Captivate, and here is my first attempt in creating something out of it. The outcome is not that clean or professional but I think it is enough to get the message across. A Simulation using Captivate to teach how to use Shared Library Assets across multiple SWFs in Flash MX and above.
You can download the captivated SWF file to view it offline. I have not used audio to save some bytes but the simulation is cool enough to explain things in itself. I suggest downloading all of them.
